ABC if median from B and C are perpendicular, then the value of cot B + cot C can be

cot A+cot B+cot C

a cot A+b cot B+c cot C=

In a Delta^(Ie)ABC, if sin A sin B sin C=(1)/(3) then the value of cot A cot B+cot B cot C+cot C cot A is

If A+B+C=0, then the value of sum cot (B+C-A) cot (C+A-B) is equal to

If the median AD of triangle ABC makes an angle (pi)/(4) with the side BC, then find the value of |cot B-cot C|
